+The HISTOGRAM subcommand causes the output to include a histogram for
+each specified variable. The X axis by default ranges from the
+minimum to the maximum value observed in the data, but the MINIMUM and
+MAXIMUM keywords can set an explicit range. The Y axis by default is
+labeled in frequencies; use the PERCENT keyword to causes it to be
+labeled in percent of the total observed count. Specify NORMAL to
+superimpose a normal curve on the histogram.

+The PIECHART adds a pie chart for each variable to the data. Each
+slice represents one value, with the size of the slice proportional to
+the value's frequency. By default, all non-missing values are given
+slices. The MINIMUM and MAXIMUM keywords can be used to limit the
+displayed slices to a given range of values. The MISSING keyword adds
+slices for missing values.
